Comeback ready: Rams ink ex-Packers CB Shields

Signed as an undrafted free agent by Green Bay in 2010, Shields grew to become an effective corner for the Packers for much of the decade, making the Pro Bowl in 2014 before concussions became an issue. He suffered his fourth of his career in the first game of the 2016 season and hasn't played since.

Shields also serves as an insurance policy and depth addition in case the Rams lose both Nickell Robey-Coleman and Trumaine Johnson in free agency, which begins next week and seems likely after the agreement to acquire Peters.
